BBL™ Catalase Reagent Droppers are used for determining the presence of catalase produced by bacteria.

Catalase Reagent Droppers are used in a qualitative procedure for determining catalase activity by bacteria. The enzyme catalase is present in most aerobic and facultatively anaerobic bacteria, with the major exception of streptococci and enterococci. The enzyme catalase decomposes hydrogen peroxide into water and oxygen.

Catalase Reagent Droppers contain a hydrogen peroxide solution of approximately 3% (2.5% to 3.5%). This reagent has been frequently cited as a standard method for performing the catalase test.^1-8

Identity Specifications—The solution is colorless, clear and free of precipitate or foreign matter.

Cultural Response—Test the performance of Catalase Reagent Droppers using one of the methods described above.

Quality control requirements must be performed in accordance with applicable local, state and/or federal regulations or accreditation requirements and your laboratory's standard Quality Control procedures. It is recommended that the user refer to pertinent NCCLS guidance and CLIA regulations for appropriate Quality Control practices.

Catalase Reagent Droppers contain: (approximately) 3% Hydrogen Peroxide and 0.05% or less of stabilizer.
